Subsequently, those programs are loaded into the RAM 503, executed by the CPU 501, and consequently each configuration unit is realized.
A screen control unit 901 controls the display of the management screen. An information processing unit 902 performs, for example, the temporary saving of information and calculations. A DB processing unit 903 refers to the DB information held in the monitoring server 104 and registers it. An image processing apparatus monitoring unit 904 receives and monitors, for example, the occurrence of errors in the image processing apparatus 101. A distribution reservation unit 905 accesses the content management server 102, registers the reservation information in a distribution reservation management unit 706, and holds the presence or absence of the reservation.
FIG. 10 is a flowchart illustrating a series of process in which the image processing apparatus 101 acquires the reservation information that has been registered in the content management server 102 via the monitoring server 104, and updates the application. First, in step S1000, a service person makes the UI screen of the monitoring server 104 shift to the screen of the content management server 102, and performs registration of the update distribution reservation of the application. Next, in step S1001, the distribution reservation unit 905 of the monitoring server 104 holds the information “reservation information is present in the content management server 102”. In step S1002, the reservation information acquisition unit 606 of the image processing apparatus 101 confirms whether or not the monitoring server 104 holds the information “reservation information is present” by polling at regular time intervals.
Here, if there is the information “reservation information is present”, in step S1003, the reservation information acquisition unit 606 acquires the information of “reservation information is present”. Subsequently, in step S1004, the reservation information acquisition unit 606 acquires the reservation information. Note that, in the present embodiment, there are two types of reservation information, the reservation information of the application and the reservation information of the firmware, where the reservation information of the application includes, for example, information about the application name, the application ID, and the version. Next, in step S1005, the update condition confirmation unit 607 determines the availability of an update based on the application ID, the version, and the like of the application that has been installed in the image processing apparatus 101.
Subsequently, if it is determined that the update is unavailable and unnecessary, in step S1006, the error notification unit 608 notifies the content management server 102 about an error notification. In contrast, if it is determined that the update is available, in step S1007, the application download unit 609 requests a URL for acquiring the application of the content management server 102. Subsequently, in step S1008, the application download unit 609 acquires the application from the content distribution server 103 based on the URL that has been acquired in step S1007. Next, in step S1009, the application installation unit 610 acquires the decryption key and license information of the application that has been installed in the image processing apparatus 101. Subsequently, in step S1010, the application installation unit 610 decrypts the application based on the decryption key and the license information that were acquired in step S1009, and receives the license information. As described above, the process from the reservation of a distributed application to the update ends.
FIG. 11 is a flowchart illustrating a specific process of step S1004 through step S1010 in FIG. 10 that is performed by the image processing apparatus 101. First, in step S1101, the reservation information acquisition unit 606 acquires the reservation information from the content management server 102. Next, in step S1102, the reservation information acquisition unit 606 determines whether or not the reservation information that was acquired in step S1101 is the reservation information about the distributed application to be distributed.
If the reservation information is determined to be about the distributed application (YES), the process proceeds to step S1103. Subsequently, in step S1103, the update condition confirmation unit 607 acquires the application information that has been installed in the image processing apparatus 101, that is, the application ID, version, start-up state (start (running) or stop) from the application management unit 604. Next, in step S1104, the update condition confirmation unit 607 determines whether or not the application that matches the application ID of the distributed application included in the reservation information that has been received from the content management server 102 is present in the installed application.
If it is determined that an application that matches the application ID is present (YES), the process proceeds to step S1105, and the update condition confirmation unit 607 determines whether or not the version of the reservation application (distributed application) is later than the version of the installed application. If the version of the reservation application is determined to be later than that of the installed application (YES), the process proceeds to step S1106. Subsequently, in step S1106, the update condition confirmation unit 607 determines whether or not the license of the application that has been installed in the license management unit 605 is valid. If the license is determined to be valid (YES), the process proceeds to step S1107. Then, in step S1107, the application download unit 609 acquires a URL for acquiring the application from the content management server 102 and downloads the application from the content distribution server 103 based on the URL.
Next, in step S1108, the application installation unit 610 acquires the decryption key and license information of the installed application from the license management unit 605. Next, in step S1109, the application installation unit 610 installs the application that was downloaded after decryption by the decryption key acquired in step S1108, receives the license information, and updates the installed application. Next, in step S1110, the application installation unit 610 determines whether or not a state of the installed application before updating is in a start state based on the information that has been acquired in step S1102. That is, it is determined whether or not the operation (of the application) starts, for example, the installed application before updating (before installation of the downloaded application) is running. If the application is determined to be in the start state (YES), in step S1111, the application installation unit 610 makes the application in the start state, and ends the process. In contrast, if the state of application is determined not to be in the start state (NO), that is, it is in a stop state, the application installation unit 610 maintains the stop state and ends the process.
If no application to be matched is present (NO) in step S1104, if the version of the reservation information application is earlier in step S1105 (NO), or if the license is not valid in step S1106 (NO), the process proceeds to step S1113. Subsequently, in step S1113, the error notification unit 608 notifies the content management server 102 about an error notification, and ends the process.
If, in step S1102, the reservation information is determined not to be about the application, that is, if the reservation information is determined to be about the firmware (NO), the process proceeds to step S1114. Subsequently, in step S1114, the firmware download unit 611 downloads the firmware from the content distribution server 103. Next, in step S1115, the firmware update unit 612 decrypts the firmware. Next, in step S1116, it updates the firmware and ends the process.
The above process enables reliably executing an import update without transmitting the application information that has been installed in the image processing apparatus 101 to the content management server 102. Therefore, according to the present embodiment, even if the information that is necessary for an update cannot be transmitted from the image processing apparatus to the server, it is possible to provide an image processing apparatus that can update the application.
Second Embodiment
In the first embodiment, in step S1106 of FIG. 11, notification about an error was provided or the application was downloaded depending on “valid” or “expired” of the license of the application that has been installed in the license management unit 605. However, there are cases in which the state of license is other than “valid” in a state in which the application is installed in the image processing apparatus 101. Accordingly, in the present embodiment, a description will be given of a case in which the state of license is other than “valid”.
FIG. 12 is a diagram illustrating a combination of a state of a license held in the license management unit 605 and a state of an application held in the application management unit 604. Although four patterns, “valid”, “expired”, “not installed (with license information)”, “not installed (without license information)” are used as the state of a license in the present embodiment, the present invention is not limited thereby, and other states of a license may be used.
In this context, the term “valid” indicates a state in which the license has already been installed, and the application can be used (can start). Additionally, the term “expired” indicates a state in which the expiration period of the license has been exceeded and the application cannot be used (cannot start). Moreover, the term “not installed (with license information)” indicates a state in which the license in a “valid” or “expired” state is created in a file and the license is made in a suspended state, and the application is disabled (cannot start). Then, when the license in a “valid” state is created in a file, it is possible to eliminate the consumption of the expiration period from the time. Additionally, the term “not installed (without license information)” indicates a state in which the license in “valid” or “expired” state is created in a file and then deleted. Note that because the license information cannot be extracted if the license was delated, taking over the license information is impossible.
In FIG. 12, a column 1201 indicates the state of license. A column 1202 indicates the state of application. A row 1203 indicates that the state of license is “valid”, and the state of application is “start”. A row 1204 indicates that the state of license is “valid”, and the state of application is “stop”. A row 1205 indicates that the state of license is “expired”, and the state of application is “stop”. A row 1206 indicates that the state of license is “not installed (with license information)”, and the state of application is “stop”. A row 1207 indicates the state of license is “not installed (without license information)”, and the state of application is “stop”.
In the present embodiment, cases in which the state of license is other than “valid” are row 1205, row 1206, and row 1207. In the first embodiment, the row 1203 and the row 1204, which are the cases of “valid” in the state of license in step S1106 of FIG. 11, are targets for updates.
However, in the cases in which the state of license is other than “valid”, that is, the cases of row 1205, row 1206, and row 1207, a case in which the latest application is requested to be used soon is assumed at the timing when the license is returned to the valid state. However, in the case of row 1207, in which the state of license is “not installed (without license information)”, because the license information is not left in the inside of the image processing apparatus 101, a key that decrypts the application is not left, so that the decryption of the application is impossible. Accordingly, in the present embodiment, in addition to row 1203 and row 1204, which are “valid” in the state of license, the case of row 1205, which is “expired” in the state of license, and the case of row 1206, which is “not installed (with license information)”, are also taken as targets for updates.
However, as described above, the case of “not installed (with license information)” is a state in which the license in a state of “valid” or “expired” is created in a file and the license is made in a suspended state, and the application is disabled (cannot start). Accordingly, when the application in this state of license is updated, the state of license is created in a file from “valid” after updating and then returned to “not installed (with license information)” so as not to cause the expiration period to elapse.
Similar to FIG. 11, FIGS. 13 and 14 are flowcharts illustrating the process from step S1004 through step S1010 of FIG. 10 performed in the image processing apparatus 101. In FIG. 11 of the first embodiment, although only the application in the state of license “valid” is a target for updates, in FIG. 13 of the present embodiment, the application in the state of license “expired” or “not installed (with license information)” is also a target for updates.
First, in step S1301, the reservation information acquisition unit 606 acquires the reservation information from the content management server 102. Next, in step S1302, the reservation information acquisition unit 606 determines whether or not the reservation information is about the application. If the reservation information is determined to be about the application (YES), the process proceeds to step S1303. Subsequently, in step S1303, the update condition confirmation unit 607 acquires the application ID, version, start-up state (start or stop) of the application that has been installed in the image processing apparatus 101 from the application management unit 604. Next, in step S1304, the update condition confirmation unit 607 determines whether or not the application that matches the application ID included in the reservation information that was received from the content management server 102 is present in the installed applications. If it is determined that the application that matches the application ID (YES) is present, the process proceeds to step S1305, and the update condition confirmation unit 607 determines whether or not the version of the reservation application is later than that of the installed application.
If the version of the reservation application is determined to be later than that of the installed application (YES), the process proceeds to step S1306. Subsequently, in step S1306, the update condition confirmation unit 607 determines whether or not the state of license of the application that has been installed in the license management unit 605 is in a not installed state, in other words, it is in a state of the 1206 or row 1207. If the state of license is a not installed state (YES), the process proceeds to step S1307, and if the state of license is not a not installed state (NO), the process proceeds to step S1309. Subsequently, in step S1307, the update condition confirmation unit 607 determines whether or not the license information of the application that has been installed in the license management unit 605 remains in the history, in other words, whether or not the state of license is the state of the 1206. If the license remains in the history (YES), the process proceeds to step S1308, and a flag is set on.
Subsequently, in step S1309, the application download unit 609 acquires the URL of the download site from the content management server 102, and downloads the application from the content distribution server 103. Next, in step S1310, the application installation unit 610 acquires the decryption key and license information of the application that has been installed. Next, in step S1311, the application installation unit 610 decrypts the application by the decryption key that was acquired in step S1310, installs it, and receives the license information.
Subsequently, in step S1312, the application installation unit 610 determines whether or not the flag is on. When the flag is on (YES), in step S1313, the application installation unit 610 creates a file of the license and stops the consumption of the expiration period. In other words, it makes the license of row 1206 be in a non-installed state (with license information). Next, in step S1315, the application installation unit 610 determines whether or not a pre-update state is in a start condition based on the information that was acquired in step S1302. If the pre-update state is in the start state (YES), the process proceeds to step S1316, and the application installation unit 610 makes the state of application be in the start state, and ends the process. In contrast, if the flag is not on in step S1312 (NO), and if the pre-update state is not the start state in step S1315 (NO), the process ends as-is.
Additionally, if it is determined that no application to be matched is present in step S1304 (NO), if the version of the reservation application is determined to be earlier than that of the installed application (NO), or if the license is not left in the history (NO), the process proceeds to step S1314. Then, in step S1314, the error notification unit 608 notifies the content management server 102 about an error, and the process ends.
In contrast, in step S1302, if the reservation information is not about the application (NO), that is, if it is about the firmware, the process proceeds to step S1317, and the firmware download unit 611 downloads the firmware from the content distribution server 103. Next, in step S1318, the firmware update unit 612 decrypts the firmware, and in step S1319, it updates the firmware, and process ends.
The above process enables reliably executing an important update even if the application in which the license has expired or is in an invalid state is present in the applications that have been installed in the image processing apparatus 101. Therefore, according to the present embodiment, it is possible to provide an image processing apparatus that can update the application even if the information required for update cannot be transmitted to the server from the image processing apparatus.
